Abstract

A remote unit for a remote meter reading system. The remote unit initiates a telephone call to a central complex at a predetermined callback time. In response to an acknowledgement signal indicative of a completed connection, the remote unit transmits indicia of its identity and collected data. The central complex responds with an instruction word, to control the next scheduled callback time and operational mode of the remote unit. Error code, load management and demand metering provisions are disclosed.
